3. Guarantee measures for cold rolling equipment management and maintenance
In the continuous development of automation and intelligence today, cold rolling equipment has gradually added more electronic components and sensors, to achieve the continuous improvement of equipment functions, convenient operation at the same time, but also brought challenges to professional maintenance personnel. Professional and technical personnel not only need established experience, at the same time also take the initiative to understand new equipment, learn new knowledge, optimize equipment, improve equipment performance. According to our company's many years of experience in equipment management and the establishment of management documents, comprehensive consideration of the comprehensive management of equipment, operation and maintenance experience, put forward the cold rolling equipment management and maintenance guarantee measures.
(1) Scientific equipment selection.
"The work is good, must first benefit its instrument", the key of scientific equipment selection is to see whether the technology and equipment is advanced, the key is to see whether the performance of the equipment can reach the optimal, if the improper selection, once put into production, need to solve the equipment design, assembly and other problems, cost
Manpower and financial consumption, seriously affect the late equipment management and maintenance. Before selecting the equipment, we should focus on considering the production capacity, the use of environment and other factors related to production. We should collect information through many ways and choose the special equipment with advanced technology and a long brand history to ensure that the service life can meet the actual production needs.
(2) Strengthen the management and maintenance of equipment use.
① Arrange the use of equipment reasonably, and constantly improve the equipment management rules and regulations. Equipment management and maintenance has been implemented as an important guarantee in the production of enterprises, overhaul, maintenance, maintenance is the premise of good operation of cold rolling equipment, but also the core and focus of equipment management, to ensure the cooperation between the professional production factory and responsible for maintenance and maintenance units, the use of scientific sequential management methods, Ensure that maintenance work has rules to follow and rules to comply with.
(2) Attach importance to the construction of the maintenance team, create an excellent learning and research atmosphere, guide the majority of operators to develop the habit of monitoring who uses who, and strengthen the monitoring of mechanical equipment. At the same time, through the teaching mode of wearing a help and learning belt, professional people can explain maintenance related knowledge, cultivate the knowledge quality of new maintenance personnel, and expand the scope of maintenance knowledge. Pay attention to the maintenance team construction, carry out skills training, organize technical personnel exchanges, improve the skill level of maintenance groups, implement the responsibility to individuals, adhere to the equipment inspection, spot inspection system. Professional personnel should also take the initiative to conduct self-inspection, analyze the progress and improvement aspects every day, and be able to quickly find special maintenance solutions, so as to combine the responsibilities of post spot inspection and professional spot inspection.
(3) Pay attention to the skill operation of equipment maintenance personnel, and improve the integrated operation and maintenance skills in various ways. Provide regular training for equipment management and maintenance personnel to improve their skills, including equipment operation procedures, equipment running state monitoring methods, equipment fault handling methods, equipment maintenance skills, new processes, new technologies, new materials, equipment hidden trouble detection methods, etc. As cold rolling equipment is a special type of professional equipment, its assembly and debugging need to follow up the whole process of the manufacturer, and the purchaser should send maintenance personnel with strong learning ability to communicate and learn with professional debugging personnel, understand the installation of parts, and communicate with professionals about possible failures and the causes of failures. Track the production of equipment, observe the equipment failure phenomenon, consult the relevant information, consult the relevant field technical personnel, combined with the actual field equipment failure, constantly to explore, explore, step by step to solve the problem, improve the level of equipment management and maintenance.
(3) Carry out management and maintenance according to the working characteristics of cold rolling equipment.
According to the cold rolling equipment vibration, fastener easy to loose characteristics of maintenance. Regularly check and tighten the screws at the inlet and outlet of the rolling mill and all the internal equipment, the pipe clamp of the hydraulic pipeline, the joint of the hydraulic pipeline, the electrical limit, the plug, etc. For wearing parts, fatigue, aging parts, regular replacement. For example, the coupling of lubrication, cooling and hydraulic system is replaced regularly; Check the roller cleaner scraper, hydraulic pipeline hose frequent action parts, large bending, force parts, found wear, regular replacement. Regularly check the oil-gas lubrication state of the roll, the state of the pin shaft in the frequently moving part, the weld of the stressed part, and regularly adjust the Angle of the plate surface purge.
(4) Establishment of maintenance warehouse.
As cold rolling equipment is a large machine composed of equipment with different functions, its internal parts are intricate and often present integration and interference distribution. Therefore, according to the transmission situation between parts, it has a very practical meaning to establish equipment data files targeted, which mainly covers the following contents:
① Device file card. Inside the file card are detailed records of the manufacturer's information as well as the specifications and use requirements of various parts, so as to prepare for the subsequent management, repair and maintenance of equipment.
② Maintenance records. Record the cause of equipment failure, maintenance and treatment methods, adopted means and fault prevention measures, in view of the problems of frequent failures, carry out technical transformation, reduce the probability of equipment failure.
③ Emergency plan. Formulate treatment and prevention plans for equipment faults such as emergency tape break and limited space operation, and reasonably use various equipment fault treatment plans in the process of dealing with emergencies. For important parts, the processing cycle is long, can not temporarily handle the use of spare parts, make plans, prepare in advance.
④ Set up equipment ledger to record technical modification or update. Establish a ledger to count the phenomena, processing processes and solutions of each equipment problem, form a maintenance problem library, provide basis for future work, and propose equipment improvement plans for the maintenance problem library.
⑤ Centralized management of equipment data, parts data, and timely update. The basis of equipment management and maintenance comes from the equipment data, complete equipment data is the premise of equipment management, do not understand the equipment structure, working principle, operating procedures, technical documents, standard parts details and wearing parts drawings, in addition to equipment spare parts or fault maintenance, the impact is very big, looking for spare parts, time-consuming and laborious, can not guarantee the timeliness of maintenance.
(5) Actively promote the application of innovative maintenance technology.
Professionals engaged in cold rolling equipment management and maintenance should take the initiative to learn and apply advanced maintenance technology, scientific management, take precautions, find and solve problems when they sprout. According to different parts, different working conditions, the selection of reasonable economic lubricating oil, lubrication mode, and lubrication cycle. The use of new technology, such as, in the removal of screws when the application of pneumatic wrench, in the equipment lubricating oil, the application of pneumatic butter gun, in the application of thread glue, liquid raw material belt, cylindrical glue, in the selection of coiling-aid equipment quality, the selection of new technology and new materials, PU material, no joint replacement of the previous nylon cloth material joint.
